Benefits of technology

[0004] A primary object of the present invention is to provide a receptacle with overload protection, so that an open circuit is formed at the receptacle when an electric appliance plugged therein is overloaded.

Problems solved by technology

However, when a certain electric appliance plugged to a receptacle connected to a part of the indoor wiring is in a current overload condition, a temperature rise would occur at that part of indoor wiring and the receptacle to even result in damage of the electric appliance or some worse condition, such as fire.

Embodiment Construction

[0012] Please refer to FIGS. 2 and 3 that are exploded and partially assembled perspective views, respectively, of a receptacle with overload protection according to a preferred embodiment of the present invention. As shown, the receptacle of the present invention includes a main body 1, a cover plate 2 closing a top of the main body 1, and a bimetallic member 3.

[0013] The main body 1 is internally provided with at least one pair of spaced elastic contact plates 11, and two fixing seats 13, 14 electrically connected to the two elastic contact plates 11. The two fixing seats 13, 14 are provided on a top with a screw hole 131, 141 each.

[0014] The bimetallic member 3 includes a first end in the form of a straight plate 31, on a free end of which there is provided a fixing hole 311; and a second end in the form of a downward extended L-shaped plate having a horizontal bent section 32 extended toward and in parallel with the straight plate 31. The bent section 32 is also provided at a ...

Abstract

A receptacle with overload protection includes a bimetallic member mounted on two fixing seats electrically connected to two elastic contact plates of the receptacle. The bimetallic member includes two contacts that normally contact with each other to form a close circuit in the receptacle. When an electric appliance plugged into the two elastic contact plates is overloaded to cause a temperature rise in the receptacle, the two contacts of the bimetallic member automatically separate from each other to form an open circuit in the receptacle, so that power supplied to the electric appliance via the receptacle is interrupted to protect the electric appliance and the receptacle from damage due to overload. The two contacts of the bimetallic member automatically contact with each other again when the temperature at the receptacle is lowered to a safety range.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a receptacle with overload protection, and more particularly to a receptacle overload protection adapted to automatically form an open circuit in the receptacle to cut off power supplied to an electric appliance via the receptacle when the electric appliance is overloaded, and automatically form a close circuit again when the overload condition disappears. BACKGROUND OF THE INVENTION [0002]FIG. 1 shows a conventional receptacle via which public power is supplied to an electric appliance plugged thereto. The conventional receptacle includes a main body 1 internally provided with one or more pairs of spaced elastic contact plates 11 and a conductive plate 12 electrically connected to the elastic contact plates 11. After a power cord is connected to the conductive plate 12, a cover plate 2 is closed onto a top of the main body 1. When an electric appliance is plugged into the elastic contact plates 11, power is supplied to ...
